Australia has a developing but substantive infrastructure of chemsex-aware services, particularly in Sydney and Melbourne. The services below are non-judgmental, LGBTQ+-aware, and experienced with the specific context of drug use in sexual settings.
For drug mechanics, overdose protocols, harm reduction, and the post-session checklist, check the following article:
Emergency
000 — for overdose, unconsciousness, respiratory depression, or suspected GHB/GBL overdose. Do not wait.
Note on GHB/GBL: Overdose is rapid and can cause unconsciousness within minutes. If someone becomes unresponsive after taking G, call 000 immediately. Place them in the recovery position. Do not leave them alone.
Note on the Good Samaritan laws: In most Australian states and territories, people who call 000 in a drug overdose emergency are protected from minor drug possession charges. Fear of police should not stop you from calling an ambulance.
Sydney
ACON — Drugs and Alcohol Programs
ACON offers counselling, harm reduction information, and referral pathways specifically for gay and bisexual men using drugs in sexual contexts. Their "Party and Play" harm reduction materials are frank and practical.
Tel: (02) 9206 2000 Website: acon.org.au
Sydney Sexual Health Centre (SSHC)
The clinic has staff experienced with chemsex presentations. If you're attending for an STI screen or PrEP and chemsex is part of your context, mention it — they can connect you with appropriate support and ensure you get the right test panel (three-site, plus hepatitis C serology, which is elevated in chemsex contexts).
Website: sshc.org.au
NUAA (NSW Users and AIDS Association)
Peer-run harm reduction organisation covering all drug use including chemsex drugs. Non-judgmental by design — peer workers have lived experience.
Tel: (02) 8354 7300 Freecall: 1800 644 413 Website: nuaa.org.au

Testing After Chemsex
Chemsex typically involves multiple partners, which makes a thorough three-site panel essential — throat, rectal, and urethral testing for gonorrhoea and chlamydia, plus HIV, syphilis, and hepatitis C. Asymptomatic infections are common.
Hepatitis C: Elevated hepatitis C transmission occurs in chemsex contexts, particularly with any blood contact (including minor trauma). Include hepatitis C serology in your test panel if chemsex is part of your pattern. Hep C is now curable in 8–12 weeks with direct-acting antivirals.
